M y 3, 932. J. H. DOMKEE I 1,35696g6 SLIDE BUCKLE Filed July 16, 1931 JUL-IN |l. DIIIMKEE Patented May 3, 1932 UNITED STATES PATENT OFFICE JOHN H. DOMKEE, OF WEST HAVEN, CONNECTICUT, ASSIGNOR TO THE VIBE NOVELTY MANUFACTURING COMPANY, OF WEST HAVEN, CONNECTICUT, A CORPORATION OF CONNECTICUT SLIDE BUCKLE Application filed July 16,

This invention relates to slide buckles used for adjusting the length of looped straps, webbing and the like, without penetrating the material, the invention relating especially to that class of slide buckles made of wire bent to form a pair of loops connected at one side and free at the opposite sides and having intermediate bar portions integrally extending from the free sides of the loops to the connected side thereof.

The objects of the invention are to provide a reversible slide buckle of the pair of loops type having fixed intermediate bar portions; to provide the intermediate bar portions of such a slide buckle with angular formations extending in opposite directions along the plane of the slide buckle; to provide means for securing together the free sides of such a pair of loops; and to provide means for securing the wire ends of such intermediate bar portions to the connected side of the loops. Vvith these and other objects in view as may become apparent from the within disclosures, the invention consists not only of the particular form herein pointed out and illustrated in the drawings, but readily admits of certain modifications within the scope of what hereinafter may be claimed.

The character of the invention may best understood by reference to one illustrative device embodying the invention and illustrated by the accompanying drawings in which the Figure 1 is an upright elevation of the device; and the Figure 2 is a side elevation thereof.

The device about to be described is an improvement on the ordinary slide buckle havin g humps projecting out of the buckle plane, and more particularly of the devices disclosed by the Patents Numbered 1,810,647 and1,762,- 263 issued to the same petitioner June 16, 1931, and June 10, 1930, respectively, on slide buckles of which the intermediate bars are provided with angular formations project "ing in planes perpendicular to and out of 1931. Serial No. 551,116.

which a middle portion provides the connect ing side 1 of a pair of loops 2 and 3 lying within a common plane and formed by bending both wire end portions in substantial parallel relation to provide the upper horizontal bar 1 and the lower horizontal bar 5' of the pair of loops 2 and 3, both wire end portions again being bent, but inwardly toward one another, to provide the relatively free sides 6 and 7 of the pair of loops 2 and 3, and both wire end portions again being bent inwardly substantially parallel with the upper and lower horizontal bars 4 and 5 to leave the free sides 6 and 7 in substantial relative engagement and to provide the intermediate bar portions 8 and 9 of'the pair of loops 2 and 3, the

intermediate bar portions 8 and 9 each being provided with spaced angularformations, 10 and 11, projecting in opposite direct-ions along the common plane of the pair of loops 2 and 3, the wire extremities 12 and 13 engaging the connecting side 1 within said plane. While the angular formations 10 and 11 may be of any desired form, the intermediate bar portions 8 and 9 are illustrated as extending integrally from the free sides 6 and 7, respectively, of the pair of loops 2 and 3 for a short distance in substantial parallel relation, one to the other, as at 14:, each intermediate bar portion 8 and 9 then being bent, as at 15, at an angle in opposite directions away from one another and along the common plane of and within the loops 2 and 3, respectively, and each intermediate bar portion 8 and 9 then being again bent, as at 16, at an angle, each in opposite directions toward one another along said plane and together providing the projections 10 and 11 extending into the loops 2 and 3, respectively, within the plane of said loops, the intermediate bar portions 8 and 9 continuing to be so bent to provide the desired number of spaced projections 10 and 11 extending substantially across the slide buckle in undulating form, r

connecting side 1 of the pair of loops 2 and 3, as aforesaid. To prevent accidental or wanton separation of the free sides 6 and 7 of the loops 2 and 3, the engaging metal surfaces at the free sides 6 and 7 are united, as at 17, in permanent intimate union, as by Welding, brazing or soldering so that the original character of said metal surfaces cannot be restored by any force effecting a mere separation of the loops 2 and 3 at that place, and the engaging metal surfaces of the extremities 12 and 13 and the connecting side 1 are likewise united in permanent intimate union, as at 18, within the buckle plane to provide a rigid structure of the aforesaid form that is reversible in the sense that the elevation opposite to that illustrated by the Figure 1 is substantially identical to the elevation as thus illustrated.

\Vhile the relatively engaging metal surfaces of the loops 2 and 3 at their free sides 6 and 7, and the engaging metal surfaces of the extremities 12 and 13 of the intermediate bar portions 8 and 9 and the connecting side 1 are illustrated and described as being preferably united in permanent intimate union, these engaging parts of the device may each be relatively secured, if desired, in any less permanent and intimate manner that may be suggested by mechanical skill.

Distinguishable from the more ordinary form of buckle having intermediate bar structures providing spaced humps protecting out of the buckle plane, the device above described, embodying as it does an intermediate bar structure providing spaced humps projecting from the intermediate bar structure but confined to the buckle plane, pro vides a perfectly flat device of as great strap gripping efficiency as that of the more ordinary form, the detour of a strap threaded in each being identical, other proportionsof the ordinary and the improved slide buckles be ing equal.

I claim: 7

1. A slide buckle comprising a pair of loops in a common plane, the loops being connected at one side and free at their opposite sides, the loops including intermediate bar portions, each extending in undulating form across the buckle and which provide spaced projections extending into both loops and confined to :aid plane;

2. A slide buckle comprising a pair of loops in a common plane, the loops being integral- 1y connected at one side and relatively free at their opposite sides, the loops including intermediate bar portions integrally extending from the free sides to the connected side,

and projections provided by the intermediate bar portions and extending into both loops and confined to said plane;

3. A slide buckle comprising a pair of loops in a common plane, the loops being integrally connected at one side and relatively free at their opposite sides, means relatively securing said free sides, the loops including intermediate bar portions integrally extendconnected at one side and relatively free at their opposite sides, means uniting the interfacing metal surfaces of the free sides of the loops in permanent intimate union, the loops including intermediate bar portions integrally extending from the united sides to engage their extremities with the integrally connected side, projections provided by the intermediate bar portions and extending .into both loops and confined to said plane, and means uniting in permanent intimate union the engaging metal surfaces of said extremities with the engaging metal surface of the integrally connected side of the loops.
